SHOE-SUPPORT.

. and particularly to a type of work support for use in connection with machlnes for working upon shoes. Herein the invention is shown and described as applied to a lasting and nailing machine which is fully eX- plained in my application Serial No. 100,556, filed March 29, 1902, of which this application is a division but it is to be understood that many features of this invention are of more general utility and are not confined in their application to the present embodiment thereof which is illustrated for the purpose of explanation and description.

An important feature of this invention is found in the novel toe and heel clasps by which the shoe ends are embraced. These clasps serve to hold the shoe for subsequent operation upon it and they also do, or may, conform the shoe upper to the portions of the last which they embrace and may serve to hold securely the upper which maybe stretched up between them and the surface of the last. In this contemplated use they do so hold the upper which may be pulled up by pincers or otherwise, and thus retained under tension by the clamping'efl ect of the clasps While the marginal portion of the upper is formed over the last bottom by wiping mechanism. The clasps then continue to hold the upper in lastedposition while the shoe is transferred to a fastening mechanism and while it is being tacked in lasted position.

Another novel feature of this invention is found in the means for operating the clasps. Preferably the toe and heel clasps are connected together so that they can be closed by a single operation. This saves time in jacking the shoe. Also preferably there is means for effecting initial or approximate closing and additional means for effecting final clos ing. As shown a lever is arranged for oper- Specification of Letters Patent. Patented June 25, 1912.

Divided and this application filed October ation to bring the two clasps together for closing the clasps about the heel and toe of the shoe. The upper, counter or linings may require some attention at the heel, as, for example, the ends of the counter wings usually need pulling up to the right height to be lasted over properly. At the toe the upper usually requires some stretching by pincers or otherwise. This can be done by drawing the upper up between the clasp and the face of the last, and the toe clasp will retain it so stretched and will conform it smoothly to the shape of the last. A cam is arranged between the lever and the clasps to be positioned during theinitial closing movement in accordance with the size of the shoe. This cam, which is provided with an operating handle, is now turned to effect final closing of the clasps with a clamping pressure that will enable them to hold the upper securely while the shoe is being overwiped by the lasting apparatus and while it is being transferred to and being operated upon by the upper fastening apparatus An advantageous feature of this invention consists in means for automatically centering or positioning the toe and heel clasps like, or each appropriate, distances from the adjacent toe or heel support where the clasps are open. and removal of the shoe.

A further feature of this invention is found in the side clamps which are adapted to hold the upper against the sides of the last between the toe and heel clasps. Preferably these side clamps are made sectional to adapt themselves to the different contours of last sides and preferably also each section is supported for movement about a vertical pivot further to facilitate adaptation to the last shape The side clamps are yieldingly closed against the shoe and means'is provided cooperating with opposed side clamps for holding them open during the removal of one shoe and insertion of another.

In the illustrated embodiment of the in vention, a plurality of shoe supports or jacks are mounted on a carrier by which a shoe is moved away from the lasting mechanism and into operative relation to the fastening mechanism. Simultaneously with this movement another shoe support is returned from the fastening mechanism and This facilitates the application --The side clamps and the end clasps are employed, in accordance with a feature of this lnvention which appears more fully in the parent case, as a guide for the tacker. In the contemplated use the tacker has a' feeler which engages the clamps and clasps lat erally and also from above and serves to position the tacker for the bottom and side contour of the last. The provision of this guide avoids the friction on the leather of the shoe which would result from direct engagement of the feeler with the shoe. Forv this purpose and to clamp all portions of the upper along the sides of the shoe in position to be lasted over by the fastening mechanism, the post that supports the front section of the side clamps carries supplementary clamping sections, one or more of which can be moved into operative position between the toe clasp and the adjacent end of the side clamp.

These and other features of this invention, including certain details of construction and combinations of parts will more fully appear in connection with the following description of the illustrated work support and will then be pointed out in the claims.

In the drawings-Figure 1 is a top or plan view of a machine containing one embodiment of my invention, the right-hand end of the machine, Fig. 1, being the front of the machine opposite which the operator stands while operating the machine; Fig. 2 is a left-hand side elevation of the shoe sup ports and mechanism for rotating the same; Fig. 3 is a front elevation of said machine, the view being taken from the right Fig. 1; Fig. 4 is an enlarged front elevation of one of the last or shoe'supports, the outline of a last or shoe being shown in dotted lines in said figure; Fig. 5 is a top or plan view of the parts shown in Fig. 4; Fig. 6 is a lefthand end elevation of the parts shown in Figs. 4 and 5; Fig. 7 is a perspective detail showing some of the parts of Figs. 4 to 6 inclusive, said figures being hereinafter referred to; Fig. 8 is a perspective view showing the lasted upper or shoe while clamped preparatory to fastening.

Referring to the drawings in which my invention is shown in connection with the machine of my prior application above re ferred to, A is the bed, of suitable shape and construction to sustain the various parts of the machine. Upon this bed A is erected a suitable column a, the upper end of which is provided with a vertical pivot stud a shown in dotted lines, Fig. 2, and upon which is pivoted to rotate horizontally the carrier B. This rotating carrier B carries a plurality of last supports, herein shown as two in number and of similar construction, hence a description of one will be suflicient, it being understood that corresponding parts of both supports are similarly lettered.

Referring particularly to the last support at. the right, Fig. 1, and also to Figs. 4 to 7 inclusive, said last'supportconsists of a movable base 7), shown as a turn table, having a depending pivot or journal stud b loosely journaled in the end of the carrier B, said table consequently rotating about a vertical axis in the carrier B which latter is itself rotatable.

Referring now particularly to Figs. 4 to 7 inclusive, the table 6 at one side has erected upon it a stationary post If, threaded at its upper end to receive the rotatable nut 6 the upper end of which is provided with a suitable heel pin 6 adapted to enter the usual socket in the heel end of a last, to hold the latter in position as indicated in dotted lines, Fig. 4. Rotation of the nut 6 causes vertical adjustment of the heel pin 6* and corresponding vertical adjustment of the heel end of the last. At its side opposite the heel support described, the table I) is provided with a second post 6 recessed at its upper end to receive freely the lower end of the vertical adjusting screw Z), supporting at its upper end the toe rest or block b of suitable shape and construction to support properly the toe end of the last, as indicated in dotted lines Fig. 4. A nut Z2 threaded upon the screw 6 rests upon the upper end of the post 12 and supports the screw and the toe rest 6 thereon in proper adjusted position. Rotation of the nut causes vertical adjustment of the screw and likewise of the toe rest If, to accommodate the various lasts. The toe rest is restrained from rotation and is guided in its vertical movement by two guide rods Z)", which work in suitable apertures in the top of the post 6 Cooperating with each last support are similarly constructed clamping or holding means which I will now describe, referring still to Figs. 4 to 7 inclusive, said clamping means, as I have herein chosen to illustrate the same, constituting also a guide or track which conforms to the outline of the bottom of the last. The heel post 6 carries a horizontal pin 0 upon which are mounted, at opposite sides of the post,like levers 0', the upper ends of which are connected by links 0 with the free ends of the heel clasp,

back of the heel, as indicated at 0 Fig.

Movement of the levers c away from the heel of the last in the direction of the arrows thereon, Figs. at and 5, causes the heel clasp members 0 to open and release the heel of the last and the material thereupon opposite or forward movement of said levers acts to close the heel clasp tightly about the heel end of the last and the material thereupon. The toe post is likewise provided at its base with a transversely extended pin, indicated at 0 upon which are pivoted, at opposite sides of the post, similar levers 0 shown as broken away in Fig. at to expose parts between the same. The upper ends of these levers c are loosely connected by links 0 with the free ends of the toe clasp members c jointed together at 0 in a manner similar to that described with reference to the heel clasp members. Movement of the levers 0 in the direction of the arrows thereon away from the toe of the last acts to separate and open the toe clasp members away from the toe of the last, and opposite movement thereof toward the toe of the last acts to close the toe clasp members about the last and the material thereupon. The clamps for the sides of the last are shown as composed principally of the links or members (Z, cl, (Z flexibly connected or jointed together, as shown in Fig. 5. The links (Z and d at opposite sides of the last, and consequently the connecting links (Z are pivotally supported by vertical screw bolts upon the upper ends of levers d, (1*, the levers (Z being rigidly secured to like and parallel horizontal shafts d, Fig. 5, jour naled in suitable bearings on the table 7:, while the levers (Z are loosely mounted upon the said shafts, but are connected therewith each through the medium of a pin ti playing in a recess or pocket (Z of a collar (Z fast on its shaft 6Z \Vhile every rotative movement of either shaft (Z is communicated to its lever (Z the lever (Z thereon is moved only when the walls of the pocket (5 in the collar (Z contact with one or the other side of the pin (Z so that there is a certain amount of lost motion between the levers (Z' and their respective shafts (Z to enable the side clamps the more readily to fit the varying contours of the lasts, along the sides thereof. Obviously the number of links or members composing the side clamping devices, and the shapes thereof, may be varied as desired and according to the various contours of lasts upon which it is necessary to clamp the material. The levers (Z (Z are provided respectively with heels (Z between which and the table are interposed suitable springs d which tend constantly to throw the upper ends of the levers and the clamp 'ing members carried thereby inwardly, to

ward and against the sides of the lasts or the material thereupon. To remove the le vers and clamping members from the sides of the lasts, I have provided the toggle levers (Z Fig. 5, connecting the levers at opposite sides of the last, and which when straightened separate the said levers and by rotating the shafts (Z also separate the levers d and consequently the side clamping members (Z, d, (Z To operate the toggle levers d, I have provided the operating lever (Z pivoted at (Z to a post erected on the table, said lever having an arm 6 which is connected with suitable actuating mechanism which will be hereinafter described. Todraw the toe and heel clasps toward their respective ends of the last, I have provided the bail 0 having its ends jointed respectively to the heel clasp levers 0'. Connected with the crown of this bail is the rod 0 which is extended "horizontally through a vertical slot in the toe post 6 see Fig. t. A spring 0 is interposed between one face of the toe post 6 and a collar 0 fast on the rod 0 and a spring 0 is interposed between the opposite face of the said toe post I) and a yoke 0 connecting the like toe clasp levers c, said springs tending normally to equalize or center the bail and rod 0 with reference to the toe post The outer end of the rod 0 at the left, Fig. t, is provided at its under side with ratchet teeth 0 adapted to be engaged by a dog 0 on a collar 0 slipped upon the said rod 0' This collar, held by said dog, serves as a back support for a face cam c surrounding the rod 0 and provided with a suitable handle 0 by which it may be rotated about the rod 0 Rotation of this face earn 0 in one direction, for instance, upwardly, as indicated by the arrow, Fig. 6, causes its cam face tocooperate with a corresponding face on the yoke 0 to force the said yoke and the toe clasp toward the toe of the last, and at the same time draw the rod 0 and the bail 0 in the opposite direction simultaneously to draw the heel clasp against the heel end of the last, thereby simultaneously clamping the material at both the heel and toe ends of the last. Opposite movement of the handle 0 and its cam 0 effects a release of the heel and toe clamps or clasps. By means of the dog 0 the position of the collar 0 011 the rod 0 may be varied to accommodate the toe and heel clasps to lasts of varying lengths. To facilitate the release of the heel and toe clasps I have extended the toggle joint pin al Fig. 5, verticall above the to le levers so that when the said toggle is straightened to release the said clamps, the inwardly moving pin (5 will act upon the cam surface 0 of the lever 0 pivoted at 0 to the bail, and will lift the said lever causing its free end to engage the tail of the dog 0 and disengage the said dog from the ratchet teeth on the rod 0 thereby freeing the collar 0 and face cam 0 and permitting the springs 0 0 to throw the heel and toe clasps quickly away from their respective ends of the lasts. After the parts have been thus released, obviously it is necessary to return them approximately to their former positions before rotation ofthe face cam 0 will become operative to clamp the toe and heel clasps against the opposite ends of the last, and to accomplish this quickly I have provided the lever 0 Fig. 4, pivoted at 0 to the base of the post b and which, when struck by the hand of the operator, operates to push the collar 0 and the cam'c the yoke 0 its levers 0 and the toe clasp quickly to the right, until the toe clasp-brings up against the toe of the last, when the parts are automatically locked in that position by engagement of the dog 0 with the ratchet teeth on the rod 0 Thereafter, rotation of the cam 0 about the rod 0 will draw the heel and toe clasps tightly against the ends of the last as described. To enable the toe and heel clasps to be moved toward and from each other to meet varying lengths of last, that is, to meet various sizes of lasts, I prefer to make the toe post 6 adjustable on and with reference to the table 5, said post being herein shown as provided with a base in the form of a dovetail slide shown best in Fig. 6, it sliding between correspondingly shaped guides on the table I). A dog 6 pivoted to the base of the toe post 19 is held by a spring Z9 normally in engagement with a series of ratchet teeth 6 shown in dotted lines, Fig. 4, and formed in or on the table 6, whereby the post 5 is prevented from accidentally moving too close to the heel post, as for instance during the time when the last is removed from the support, said dog, however, not interfering with the free movement of the toe post away from the heel post when necessary to accommodate longer lasts. This relative adjustment of the toe and heel clasps to accommodate lasts of different lengths necessarily requires that the effective length of the side clamping means be extended to thereby accommodate lasts of difierent lengths, said extending means being herein represented as a series of fingers e, pivoted loosely upon pins 6 carried by the levers d3 at opposite sides of the last. Springs 6 are interposed between the respective levers (Z and the nearest fingers e to retain the latter frictionally in any position into which they are moved. When it is desired to move the toe and heel clasps closer together to accommodate a shorter last, one or more of the fingers e at each side of the last is turned down into a horizontal position, the fingers next to the toe clasp being first turned down, and thereafter the second and then the third fingers at each side of. the last. These fingers constructed as herein described serve not only as clamping members but also to preserve the continuity of the last-shaped guide or track formed about the last by the clamping members and clasps.

I will now describe the mechanism for imparting to the shoe the required rotative movement to enable the tacks to be driven as desired around the shoe.

As hereinbefore stated, the turn-tables 19 carrying the last supports'are respectively provided, as shown in Fig. 2, with depend ing pivots or journals I), which extend below the carrier B and are provided at their lower ends, as herein shown with like disks 25, between which and the underside of the carrier B are interposed friction springs t to retain the pivots and their turn-tables with the parts carried thereby, frictionally in any position into which they are moved. The peripheries of the disks 6 are shown as provided each withtwo circumferential series of holes 15 for the reception of pins of the required number, said pins being inserted in the-proper holes of their respective series to provide the necessary movements, as will be hereinafter set forth. Below the pin carrying disks 6 the pivots b are further provided with toothed wheels t, as best shown in Fig. 2. Vhen a last support is swung into position at the front of the machine, viz at the right, Fig. 2, for the lasting operation, no rotative movement of the turn-table 19 carrying the last is necessary, hence there is nothing in engagement with and to rotate the toothed wheel 25 and the disk t with the connected parts. When,

'however, the carrier B is turned to carry such last and its support around to the left, Fig. 2, in position to enable, the attaching means or tacker to operate upon the shoe, the gear wheel t at the lower end of the pivot of the turn-table is thereby swung into position ready to be engaged by the gear wheel 6 fast on the upper end of a vertical shaft 6 journaled in suitable bearings 27 at the face of the standard 0 I say the gear t is swung into position ready to be engaged by the gear t because when first swung into such position, no actual engagement takes place, the gear 6 being a mutilated gear having two blank spaces thereupon, and at the moment the gear tis swung into the position referred to a blank space of the gear 25 is in a position opposite the gear 6 so that while in position ready for engagement the actual engagement of the two gears is deferred for a time. It will thus be understood that the shoe supports have each main and auxiliary rotative means workingindependently of one another, and each controlling and eifecting a partial rotation of each shoe support during the op' eration of fastening the upper to the inner sole lying on the last held in said support. This blank space cannot be seen in Fig. 2 because it is on the back side of the gear, but the second of the two blank spaces, which is diametrically opposite the first, can be seen at the left of the gear in said figure.

The vertical shaft-t at its lower end, see Fig. 2, has fast upon it a ratchet wheel i driven intermittingly by a pawl t carried at the outer end of a pawl carriertloosely journaled about the shaft t. The pawl carrier in turn is vibrated by an eccentric rod i reaching to an eccentric fast on the driving shaft h on the bed. At each rotation of the main shaft 70 the pawl carrier is re-' ciprocated and, through its pawl, imparts a stepby-step rotation to the vertical shaft the turn-table disk.

The gear i on the upper end of the vertical shaft t, as shown, has teeth on but a portion of its periphery, there being, as stated, two blank portions arranged at diametrically opposite points of the gear, so that the said gear will mesh with the gear 25* on the pivot of the turn-table and rot-ate the latter, and the last only during certain parts of the rotation of the shaft t.

Referring now particularly to Fig. 2, the shaft t just below its upper bearing t has fast upon it awide gear t which meshes with a gear If of approximately the same diameter and also with a pinion Z of considerably smaller diameter both mounted in suitable bearings on the side of the column a. The gear t meshes directly with a gear t on the lower end ofasleeve t" journaled in suitable bearings at the interior of the column a and carrying at its upper end a disk i of substantially the same diameter as the disk 1 on the bottom of the turn-table pivot, but approximately one-half of the thickness of This disk 6 has its periphery provided with a series of holes for the reception of pins The pinion t referred to as driven by the gear 6 meshes with an intermediate pinion 75 which in turn meshes with a gear fast on the lower end of a shaft Z within the sleeve i referred to and provided at its upper end and above the disk 25 with a similar disk 6' having its periphery provided with holes for the reception of pins t; Obviously, rotation of the vertical shaft 5 acts through the mechanism described to rotate the sleeve 6" and disk r in one direction, for example, as indicated by the arrow thereon, while the same shaft and gear operate through the pinions t and t to rotate the shaft 5 and the disk t in an opposite direction, as indicated by an arrow on the disk. The positions of the pins in the disks and Z and in the disks 25 on the bottoms of the turn-table pivots are such that during the period when the turn-table is not rotated directly from the vertical shaft t by the mutilated gear 29,

that is, during the time that a blank space on the gear t is passing the gear i on the lower end of the turn-table pivot, the pins, either of the disk 6 or of the disk will engage cooperating pins on the disk 25 on the turn-table pivot and impart to the latter a step-by-step rotation in one or the other direction according to whether the pins which impart the rotation are on the disk or on the disk t.

The purpose of the mechanism just described is to produce rotat-ive movement of the shoe support in suitable time relation to the movements of the securing means to and fro over the edge of the sole, so that the line of movement of the securing means will be maintained substantially perpendicular to the edge of the sole at all points about its periphery. When, in the course of the se curing operation, the toe or the heel portion of the shoe is reached an entire semi-rotation of the shoe support is necessary to enable the securing operation to be carried on about said portion. This movement, which is combined with a backward movement of the securing means, is produced by the meshing of the toothed portion of the mutilated gear t with the pinion i there being two toothed portions on the gear a, each of sufficient length to give the pinion t and the shoe support a semi-rotation. While the securing means is operating along the comparatively straight shank portion, the shoe support is held stationary but at the junction ofthe shank with the ball portion a curve occurs which renders it desirableto rotate the shoe support to some extent in a direction reverse to that in which the semi-rota tion occurs and then to move it back again to its formerstationary position while the securing means operates along the comparatively straight side at the ball toward the toe. As described, the disks 6 and Z are rotated in opposite directions and the pins in their peripheries and those in the two rows of holes in the disk 2? are so arranged as to number and location that the shoe support is given a slight rotation to the right, Fig. 1, when the portion of the side having the greatest curvature is reached and then back again when a portion of less curvature is reached. A similar movement is made to occur while the securing means is passing along the other side of the shoe from the ball to the shank portions.

The clamps and clasps above described remain holding the uppers after the tacking has been completed, but I have provided convenient means for releasing the clamps and clasps automatically as they approach the front of the machine, in order that when brought to a state of rest the shoe is already unclamped ready for removal and for the substitution of anew shoe to be lasted.

Referring to Figs. 1 and 5, the free end of the lever d, which controls the toggle (Z and the clamping and unclamping of the toe and heel clasps, bears agalnst the edge of a helical surface cam to, Fig. 1, loosely pivoted upon the top of the pivot 64 of the carrier B. This cam has a slot to into which protrudes a stop pin 10 on the stationary pivot a, the pin and slot serving to limit the rotative movement of the said cam, which is accomplished by a suitable handle Q03 provided for the purpose. Onehalf of the cam, viz :the lower half viewing Fig. 1, is semi-circular, while the remaining or upper half is quite eccentric or helical, and as the carrier is swung to carry a lasted shoe from the position at the front of the machine at the right Fig. l into the position at the left Fig. 1, to be tacked, the roller stud shown in the end of the lever (Z travels about the concentric or semicircular portion of the cam w and holds all the clamping parts firmly in position clamping the upper to the sides of the last. After the tacking or securing operation, however, the second movement of the carrier in returning the lasted and tacked shoe again to the front of the machine while transferring a newly lasted upper to the securing mechanism, causes the lever (Z cont-rolling the clamps on the lasted and tacked shoe to travel upon the eccentric portion of the cam w, it being turned by the gradually rising face of the cam into its dotted line position, Fig. 5, and by the time the carrier has reached the end of its semi-rotative movement, the movement ofthe lever (Z will have moved the toggles d sufliciently to release the side clamping members and the toe and heel clasps and leave the shoe free for ready withdrawal by the operator. The action of the ends of the two levers d against the surface of the cam w tends constantly to move the cam in the direction of the arrow Fig. 1, into position with the right hand end of the slot w in contact with the pin ta The operator, however, having removed thelasted and tacked shoe and placed in position upon the last support a new shoe for lasting, must move the lever al to release the clamps and permit them again to grip the new upper placed in position. This the operator accomplishes by grasping the handle 10 and moving the handle and the cam in a direction opposite that of the arrow, Fig. 1, for a distance limited by the length of the slot to, but which is sufficient to enable the lever d previously held in its dotted line position, Fig. 1, to drop from the high point of the cam to the lowest point thereof, that is, onto the concentric portion, which'breaks the toggle and permits the springs 6Z1 automatically to throw the side clamps against the sides of the shoe and also permits the operator thereafter by the levers a and 0 described to bring into action the toe and heel clasps. As soon as the carrier is rotated to carry the newly lasted shoe into tacking position, the frictional engagement of the lever (F with the surface of the cam '11) moves the latter again in the direction of the arrow into its original position to unlock and hold unlocked the clamping mechanism of the tacked shoe carried to the front of the machine for removal, as described. Thus the clamps are automatically released when brought in succession from the tacking mechanism to the front of the machine, leaving the lasted and tacked shoe perfectly free for removal.

Referring now to Figs. 1 to 3 inclusive, the end lasting mechanism is constructed and arranged to operate upon the upper on the last only while the last is carried by the last support which may, for the time being, be held in the position indicated at the right of Fig. 1. Referring to Fig. 3, f, f are two treadle levers fulcrumed at f to the base of the column a. These treadle levers have connected to them, by universal joints P, the lower ends of the supporting rods f to the upper ends of which are connected by pivots f the supporting plates f which carry the lasting mechanism. This lasting mechanism may be of any suitable or desired construction capable of lasting or turning inwardly and downwardly the material at or near the ends of the last. I have herein shown such mechanism as of the wellknown wiper type, the wipers being inclicated at f, Fig. 1, they being caused to close and open as they are advanced and retracted by studs f f working in slots f ft", in the top plates f These studs are connected by links f which in turn are connected by other links f with the actuating block f which is given a forward and back reciprocating motion by and from a suitable hand lever f connected therewith by a link 7. The vertical inclination of the lasting plates for the toe and heel, to accommodate the spring at the ends of the last, is varied by means of the adjusting screws f interposed between the plates f and suitable stop surfaces formed by bending the rods F, as shown in Fig. 3. The normal positions of the end lasting devices are shown in dotted lines, Fig. 3, wherein the supporting rods f are swung apart about their respective fulcra at the universal joints f thereby removing their respective end lasting mechanisms free and clear from the last support and connected parts. The lasting mechanisms may be brought together and in close proximity to the ends of a last, preparatory to lasting, by swinging the supporting rods i toward each other into their full line positions, Fig. 3, where they are automatically caught and retained by the dogs f thereon cooperating with the locking teeth f on the locking bar f carried by the column a. These dogs may be released by the operator, for the withdrawal of the lasting mechanisms in any suitable manner, as by the handles f.

When the upper and inner sole have been assembled in the usual way upon a last, the latter is first placed upon the last support, which is at the right, 2'. 6., the front of the machine, as the operator stands at the right hand end of the machine, Figs. 1 and 2. The operator next moves the handle 0 to force the toe clasp against the toe of the last and the cam handle 0 to tighten both the toe and heel clasps against their respective ends of the lasts. He then releases the toggle (Z in the manner already described to permit the springs (Z to throw the side clamps against the material at the sides of the last, the operator at the same time, with the assistance of his pincers, or in any other suitable manner, drawing the sides of the upper upwardly about the body of the last in order that the same may be held by the side clamps in a stretched condition upon the last. With the material thus held firmly to the last in a plane or line just below the bottom of the last, or just below the line of action of the lasting wipers, the operator swings the supporting rods f carrying the end lasting mechanisms, from their dotted line positions toward each other into their full line positions, Fig. 8, thereby bringing said end lasting mechanisms up to the respective ends of the last where they can be operated to last the material thereupon. Of course the clamps and clasps referred to are still in posit-ion holding the upper to the last. The operator now, through the medium of the handle levers f Fig. 1, advances and closes the toe and heel wipers to lay the material at the toe and heel of the last, and after the material has been crimped and laid down upon the upturned bottom of the last or upon the innersole thereon, it is there compressed by depression of the treadle levers f, f, by the foot of the operator, which actthrough the rods f to correspondingly depress the entire lasting mechanisms, causing the heel and toe plates f to press the crimped and folded material tightly down upon the innersole, the compression continuing only so long as the operator holds the treadles or either of them depressed. The arrangement of the pawls f causes them to force the lasting mechanisms farther over the shoe when depression by the treadles f is effected, as will be ob vious from Fig. After the compression the treadles and wipers are raised by springs f' Fig. 2, the lasting plates are then withdrawn, and with the toe and heel clasps and side clamping members still in position clamping the upper tightly against the sides of the last, thereby holding the upper in its lasted position, the operator releases the dog f holding the lasting mechanisms up to the last, thereby permitting the lasting mechanisms to fall away from the last into their dotted line positions, Fig. .2, by their own weight, after which the carrier B is rotated to carry the last support with its lasted and clamped shoe into the position at the left, Figs. 1 and 2, for the purpose of having its upper tacked or secured permanently in position on or to the inner-sole, the shoe previously lasted and swung into such position and now having its upper permanently secured, being at the same time swung to the right into position in front of the-operator, where it is removed and a new last upper and innersole placed in position and lasted while the one previously lasted is being tacked or secured. After the securing operation has been completed, the operator swings the carrier to carry the lasted and tacked shoe again to the front of the machine, such rotation automatically releasing all the clamps which during the entire previous operation have held the upper smoothly and securely to the last, the said carrier when it reaches its proper post tion being automatically locked, Fig. 3, by

a vertically moving locking pin r in the bar F", the upper end of the said pin being conical to fit a recess in-the lower end of the turn-table pivot b. As the table swings into locking position, the end of the turn-table pivot automatically depresses the pin 1, which when it reaches the proper position is thrown upwardly by a spring r, it entering the said recess and locking the carrier in its working position. When the carrier is again to be rotated, the operator depresses the locking pin r by means of a foot treadle 1*, Fig. 3, connected by rod r with the end of the pin, and swings the carrier by hand through a semi-rotation, when. it is again locked by said pin, the trcadle in the meantime having been released by the operator.
